ok, here's my gameplan: i've got a g-4 and a g5. i'm going to install my logic pro-6 on both (moving the key back and forth as i will only use one at a time). i plan to track with the g-4 and record to my external hard-drive, and daisey chain the hard drive to the g-5 (a very long fire-wire cable will be used here). then i will open the audio on my g-5 and mix it down there in a better sounding room and with more plugin processor power. MY MAIN QUESTION: the G-5's core audio card has an opticle out. anyone know of a cost effecient way of running the mix through the optical out and end up on my monitor mix??? this is crucial,,, i can't afford another interface right now!!! any suggestions are much apprectiated!!
